Hello.

I have a Thinkpad X200 with Intel 5300 wifi card.

03:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300
        Subsystem: Intel Corporation Device 1011
        Physical Slot: 1
        Flags: bus master, fast devsel, latency 0, IRQ 48
        Memory at f2a00000 (64-bit, non-prefetchable) [size=8K]
        Capabilities: [c8] Power Management version 3
        Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
        Capabilities: [e0] Express Endpoint, MSI 00
        Capabilities: [100] Advanced Error Reporting
        Capabilities: [140] Device Serial Number 00-21-6a-ff-ff-03-8c-26
        Kernel driver in use: iwlwifi
        Kernel modules: iwlwifi

After upgrading to 3.2.0-35 from 3.2.0-34 I have problems connecting to my D-link DIR-855 on 5GHz. After rebooting the computer, I frequently have to reboot my router in order to connect. Reloading (rmmod/modprobe) iwlwifi doesn't help. I tried several times back and forth between 3.2.0-35 and 3.2.0-34 and with 3.2.0-34 I can always connect without rebooting the router, but with -35 I have yet to be able to connect directly after boot without rebooting the router. I can disconnect the wifi (bring my computer with me in suspended mode, be somewhere else and use it, and then bring it back home) and it can successfully connect. It's just the initial connect after boot that is affected.

When it's trying to connect with -35 I get the following:

After rebooting the router and rebooting with -35 again, I get the following:
